˘şApplication Information |
|
C-8 is useful in a great variety of
rigid polyurethane applications from
appliance to |
|
polyurethane boardstock to spray to pour-in-place.
The product demonstrates a preferred catalysis
of the water/isocyanate reaction with a moderate
catalysis of the polyol/isocyanate reaction.
As a result of this selectivity, C-8 is a
strong initiator of the foam reaction with
moderate blow and a low contribution to gelation.
Because of these attributes, C-8 is an effective
initiator and flow catalyst for most rigid
foam formulations. |
|
|
C-8 may be used as the sole catalyst,
but often a co-catalyst is employed.
Recommended |
|
use levels are from 0.5 to 3.5 part per
hundred of polyol depending on the reaction
profile and the physical properties desired.
